    Namotaj za razmagnetisavanje ekrana napaja se iz stepena za napajanje naizmeničnim mrežnim naponom preko otpornika sa pozitivnim temperaturnim koeficijentom (PTC) 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The explanation for the given correct answer is that a degaussing coil is powered by the AC power supply through a positive temperature coefficient (PTC) resistor. This resistor helps regulate the current flowing through the coil and prevents it from overheating. By using AC power, the degaussing coil can generate a changing magnetic field that demagnetizes the screen and removes any residual magnetism. Therefore, the statement is true.

    U opštem slučaju jednosmerni naponi od +5, +3.3 i +12V koji se dobijaju iz stepena za napajanje su potpuno nezavisni. To znači da je ograničena ukupna snaga koja se može dobiti na jednom naponu, bez obzira da li postoji, i koliko je optrećenje na drugim naponima.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    In a general case, the given statement is true. It states that in a power supply system, the individual voltages of +5V, +3.3V, and +12V are completely independent of each other. This means that the total power that can be obtained from one voltage is limited, regardless of whether there is a load or how much load is present on the other voltages. Therefore, the statement is true.

    Postavljanjem više polarizacionih filtara sa različitim uglovima polarizacije moguće je smanjiti intenzitet svetlosti i postići različite polarizacije

    • True

    • False

    Correct Answer
    A. True
    Explanation
    By placing multiple polarization filters with different polarization angles, it is possible to reduce the intensity of the light and achieve different polarizations. This is because polarization filters only allow light waves with a specific polarization angle to pass through, while blocking others. By combining filters with different angles, the intensity of the light can be decreased, and different polarizations can be achieved. Therefore, the statement is true.

    Maksimalna brzina prenosa Fibre Channel (FC) tehnologijom je (red veličine):

    • 8 Mbps

    • 8 Gbps [1,2,4 I 8 GB/S]

    • 800 Gbps

    • 80 Mbps

    Correct Answer
    A. 8 Gbps [1,2,4 I 8 GB/S]
    Explanation
    The correct answer is 8 Gbps [1,2,4 I 8 GB/S]. This is the correct answer because Fibre Channel (FC) technology has a maximum transmission speed of 8 Gbps. The options 8 Mbps, 800 Gbps, and 80 Mbps are not correct as they do not match the maximum transmission speed of FC technology. The option 8 Gbps [1,2,4 I 8 GB/S] is the correct answer as it accurately represents the maximum transmission speed of FC technology and also includes the different possible speeds within that range.

    Vidljivi deo spectra se nalazi na granicama?

    • 100-400nm

    • 700-980nm

    • 400-700nm

    • 980-1250nm

    Correct Answer
    A. 400-700nm
    Explanation
    The visible spectrum refers to the range of light that is visible to the human eye. It ranges from approximately 400 to 700 nanometers (nm). This means that light with wavelengths shorter than 400 nm (such as ultraviolet light) and longer than 700 nm (such as infrared light) cannot be seen by the human eye. Therefore, the correct answer is 400-700nm.

    Na kojim pinovima VGA konektora u monitoru se nalaze horizontalni i vertikalni sinhro impulsi?

    • 9, 10

    • 1, 2

    • 13, 14

    • 5, 6

    Correct Answer
    A. 13, 14
    Explanation
    The horizontal and vertical sync pulses in a VGA connector are located on pins 13 and 14. These sync pulses are used to synchronize the display of the monitor with the graphics card in the computer, ensuring that the image is displayed correctly on the screen.

    Maksimalna brzina prenosa Fibre Channel (FC) tehnologijom je (red veličine):

    • 400 Gbps

    • 4 Mbps

    • 40 Mbps

    • 4 Gbps

    Correct Answer
    A. 4 Gbps
    Explanation
    The correct answer is 4 Gbps. Fibre Channel (FC) technology is commonly used for high-speed data transfer in storage area networks (SANs). The maximum speed of data transmission using Fibre Channel technology is 4 Gbps, which is significantly faster than the other options listed (400 Gbps, 4 Mbps, and 40 Mbps).

    Ako je snaga stepena za napajanje dekarisana na 400W, a na vodu od 12V može da podrži struju od 18A, maksimalna snaga za potrošače koji zahtevaju napon od 12V je

    • 216 W

    • 324 W

    • 400 W

    • 144 W

    Correct Answer
    A. 216 W
    Explanation
    The given question provides information about the power of a power supply unit (PSU) and the current it can support for a 12V load. The power formula is P = IV, where P is power, I is current, and V is voltage. We are given that the PSU can support a current of 18A for a 12V load. By substituting the given values into the formula, we can calculate the power: P = 18A * 12V = 216W. Therefore, the maximum power for consumers requiring a 12V voltage is 216W.

    Učetanost horizontalnog skeniranja (HRR) meri se u kHz, a Učestanost vertikalnog skeniranja se meri u Hz?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because the horizontal scanning frequency (HRR) is measured in kilohertz (kHz), while the vertical scanning frequency is measured in hertz (Hz). The horizontal scanning frequency refers to the number of times the electron beam moves horizontally across the screen per second, while the vertical scanning frequency refers to the number of times the electron beam moves vertically from the top to the bottom of the screen per second. Therefore, the measurement units for these two frequencies are different.

    Uloga NTC otpornika na ulazu prekidačkog stepena za napajanje je da

    • Ograniči početnu struju

    • Bude naponski delitelj

    • Detektuje 220/110 V

    • Bude naponski delitelj

    Correct Answer
    A. Ograniči početnu struju
    Explanation
    The correct answer is "ograniči početnu struju." The role of an NTC resistor at the input of a power switch level is to limit the initial current.

    Perzistencija je

    • Vreme trajanja sjaja fosfora nakon pobude

    • Jedan od rasporeda fosfornih tačaka

    • Tromost elektronskog mlaza

    • Gustina fosfornih tačaka na ekranu

    Correct Answer
    A. Vreme trajanja sjaja fosfora nakon pobude
    Explanation
    The correct answer is "vreme trajanja sjaja fosfora nakon pobude" which translates to "the duration of phosphor glow after excitation." This explanation refers to the persistence of phosphor, which is the time it takes for the phosphor to stop emitting light after being excited.

    Koji visoki napon dobijamo iz Horizontalnog izlaznog stepena?

    • 25 kV

    • 50 V

    • 1500 V

    • 18 kV

    Correct Answer
    A. 25 kV
    Explanation
    We obtain a high voltage from the horizontal output stage. The correct answer is 25 kV.
